摘　　要：该文简要概述利用岩心直接判断古水流方向的重要意义,以及确定取心地层产状的方法;详细阐述了①岩心地层倾角校正,②由斜层理视产状求真产状,③以斜层理为例求倾向方位,④确定古水流方向四个方面的操作步骤。通过应用举例,证实该方法准确、迅速、有效,为现场工作人员提供了快速确定古水流方向的经验。The paper briefly summarized the importance of the direction of distinguishing palaeo water flow directly by use of core and the method of determining accurrence of core foramtion,detaily described the four working steps of①dip angle correction of core formation,②seek real occurrence from inclined bedding viewing occurence,③seek dip azimuth by the example of inclined bedding,④determine palaeo water flow direction.It proves by the examples that the method is correct,fast and effective,it can provide experience for wellsite operators to determine palaeo water flow direction quickly.
